To all whom it may concern.-

Be it known that l, THOMAS GORE, a citizen of the United States, and aresident of the borough of Brooklyn, in the county of Kings and State ofNew York, have inventedcertain new and useful improvements in Wire Ropesor Cables, cit which the tollowing is a specification.

My invention relates to improvements in wire ropes or cables, andparticularly to such ropes or cables as are used for haulage andhoisting purposes.

rlfhe main object oi2 my invention is to protect the strands ot the ropeor cable against wea-r and abrasion and this il do by interposingbetween the strands, wearing members which are provided with wearingsur-Y faces to torna portions of the workingsurtace', oi the rope.'llhese wearing members or strips are preferably so shaped 'a'sito till.

up 'the interstices between adjacent strands of the rope, and thewearing surfaces are preferably extended over the tops of the strandsmore or less so as to cover the strands and protect them trom wear andinjury. rihe wearing members are thus oi a. height at least equal to thediameter oi the twisted strands, and to permit the inner and outerportions of said wearing members to be unequally twisted, ll provideweakened parts or notches therein.r Another feature ot my inventionconsists in interlocking the wearing members between the strands in sucha way as to torna a unitary structure and to prevent the members frombecoming displaced from between the strands. This ll accomplishpreferably by making the wearing members with conn cave sides so as toclosely 'tit in the interstices between the strands, and with baseportions adapted to engage and interlock under the adjacent strands.

Various other features of the invention will appear as the speciiicationproceeds.

In the accompanying drawings is illustrated a preferred embodiment ot myinvention but various changes and n iod'itications may be made thereinwithout departing from the spirit and scope of the invention.

Like reference. characters refer to like parts throughout the severalviews.

'The rope or cable of my invention coni-* sists of a plurality ofstrands 7, between.

are preferably concave in shape so 4as to closely fit in the intersticesbetween adjacent strands and in order to more fully protect the strandsthe wearing surfaces of the strips preferably extend over and partiallycover adjacent strands (see ,particularly Fig. 2). ln order to moresecurely bind the wholatogether and to secure an interlocking actionbetween the strands and the wearing strips, the strips are preferablyprovided with portions which engage beneath adjacent strands andsecurely lock the strips in place.. This interlocking action issuch thateven it one of the wearing strips were to break, it would still beheldin place and would serve its proper function. `And in the same way,it' a strand should break, the loose ends would stilln be retained andheld between the wearing'strips.

The wearing strips may be made 'in various shapes, but preferably asshown in Fig. 3, strips 15 are used, having the two wearing surfaces 16,joined by a web lportion 17. With this form the rope is assembled asshown in Fig. 2, with the wearing surfaces outermost and the webportions 17, passing underneath-alternate strands. As the wearing stripsare usually made of iron or steel or other `stood wearingmaterial, whichmaterial may be of less flexibility than the strands themselves, then inorder not to interfere with the flexibility of the completed rope, thewearing strips may be twisted strands, each strand being made up of aplurality of wires twisted together, nd Signed at New York city in thecounty wearing strips twisted in between the of New York and State ofNew York this strands and partially overlapping the 30th day of July A;D. 1910.
